Field of the InventionThe present application relates to prostheses for use in the eye. In particular, the present application relates to prostheses that enhance or alter the appearance of a wearer's eye.2. BackgroundIt is known that the aperture of the human eye (i.e., largest vertical distance between an individual's upper lid and lower lid) reduces in overall diameter by 1.5 mm or more as one matures from that of a child to that of an adult of the age of 40 and even more as one matures to that of a senior of 60 years or older. In addition to a reduction in aperture size due to old age, some individuals suffer from blepharoptosis, also referred to as ptosis, which is defined as an abnormal low-lying upper eyelid margin within the eye in primary gaze. In some instances, ptosis is correctable by surgery. Moreover, some individuals may desire a larger eye aperture for cosmetic purposes.Traditional corneo-scleral contact lenses (soft contact lenses or hybrid contact lenses) that fit on the cornea of one's eye (do not vault the cornea) and extend over the limbus and bulbar conjunctiva thus covering part of the sclera are not being used for correcting ptosis and/or the widening of the wearer's palpebral fissure. This is due to their geometrical design. Also corneal contact lenses (rigid or soft) that fit only the cornea and do not extend past the limbus are not used for correcting ptosis and/or the widening of the wearer's palpebral fissure due to geometrical design and overall diameter. Scleral contact lenses are hard/rigid and have been designed in the past to fit snugly against the sclera of the wearer's eye, “vault the cornea” and have a very thick edge design such to lift the upper lid of the wearer's eye having ptosis. While scleral contact lenses have existed in the past that will lift the upper lid of the wearer's eye these hard/rigid sclera contact lenses are highly uncomfortable, cause very red eyes and irritate the eye lid margin thus presenting severe limitations for the wearer. For these reasons the commercial success of scleral contact lenses to correct for ptosis has been a major failure. Thus non-surgical and comfortable means to widen the natural palpebral fissure of an individual's eye are of interest.SUMMARY OF THE INVENTIONSome embodiments include a prosthesis, such as a corneo-scleral contact lens, for enhancing the look of a wearer, whereby the prosthesis includes a colored region that is one of: a colored ring, limbal ring, color enhanced iris area, accent color located over a portion of the limbus of the wearer's eye and whereby the prosthesis includes a surface feature designed to increase the distance between the upper lid margin and the lower lid margin of the eye of the wearer.

The disclosed embodiment(s) merely exemplify the invention. The scope of the invention is not limited to the disclosed embodiment(s). Multiple inventions may be described. The invention is defined by the claims appended hereto.The embodiment(s) described, and references in the specification to “one embodiment”. “an embodiment”, “an example embodiment”, etc., indicate that the embodiment(s) described may include a particular feature, structure, or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is understood that it is within the knowledge of one skilled in the art to implement such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.It is known that the aperture of the human eye (i.e., largest vertical distance between an individual's upper lid and lower lid) reduces in overall diameter by 1.5 mm or more as one matures from that of a child to that of an adult of the age of 40 and even more as one matures to that of a senior of 60 years or older. This reduction in diameter can be fixed surgically through a procedure called blepharoplasty. Presently there are approximately 200,000-300,000 blepharoplasty operations performed per year in the United States at the cost of approximately $2,500 per upper lids surgery and $3,500 per lower lids surgery. In addition to a reduction in aperture size due to old age, some individuals suffer from blepharoptosis, also referred to as ptosis, which is defined as an abnormal low-lying upper eyelid margin within the eye in primary gaze. The reduction in aperture size can affect an individual's vision. While a reduction of aperture size can affect the vision of some individuals, some individuals may desire a larger eye aperture for cosmetic purposes, either in combination with a desire to improve their vision or not.Traditional corneo-scleral contact lenses (soft contact lenses or hybrid contact lenses) that fit on the cornea of one's eye (do not vault the cornea) and extend over the limbus and bulbar conjunctiva thus covering part of the sclera are not being used for correcting ptosis and/or the widening of the wearer's palpebral fissure. This is due to their geometrical design. Also corneal contact lenses (rigid or soft) that fit only the cornea and do not extend past the limbus are not used for correcting ptosis and/or the widening of the wearer's palpebral fissure due to geometrical design and overall diameter. Scleral contact lenses are hard/rigid and have been designed in the past to fit snugly against the sclera of the wearer's eye, “vault the cornea” and have a very thick edge design such to lift the upper lid of the wearer's eye having ptosis. While scleral contact lenses have existed in the past that will lift the upper lid of the wearer's eye these hard/rigid sclera contact lenses are highly uncomfortable, cause very red eyes and irritate the eye lid margin thus presenting severe limitations for the wearer. For these reasons the commercial success of scleral contact lenses to correct for ptosis has been a major failure.Color enhancing soft contact lenses have been developed and have met with significant commercial success. These color enhancing soft contact lenses can enhance the color of the wearer's eyes. Certain soft contact lenses comprise a colored ring to make the eye of a wearer look larger when these soft contact lenses are worn. While colored soft contact lenses having a color ring or band have been used to increase the perception that the eye of the wearer is larger, no soft contact lens has been developed that both increases the perception that the eye of the wearer is larger and also physically widens the palpebral fissure of the eye of the wearer.Thus there is a need for a non-surgical comfortable means to widen the natural palpebral fissure of an individual's eye. There is also need for a non-surgical means to both open up the aperture of the natural eye that is also capable of allowing an individual blink without discomfort. And, in some instances, there is the need to restore some of or all lost visual field function in the case of ptosis due some degree of a paralysis or loss of function of the upper lid. Moreover, there is a need for a non-surgical means capable of enhancing the cosmetic look of an individual's eye(s) (e.g., maintain a youthful look or a more alert look). The cosmetic enhancement may be achieved by physically widening the natural palpebral fissure of an individual's eye (i.e., lifting the upper lid and/or depressing the lower lid) and/or providing the perception that the eye of an individual is larger.Embodiments of the present application described herein, or elements thereof, may accomplish one or more of these or other objectives.Some embodiments include a prosthesis capable of being worn on the eye of a wearer having a convex surface and a concave surface.

In some embodiments the protocol or instructions include directions to determine a vertical dimension of the wearer's natural palpebral fissure, and to provide the wearer with a prosthesis having a minimum vertical dimension at least 1 mm greater than a maximum vertical dimension of the natural palpebral fissure (such a determination can be made by, way of example only, actual measurement, photography, visual estimate, or by one of, fitting a trial prosthesis, contact lens of a known diameter, or a prosthesis of a known diameter).A prosthesis of this patent application in the form of a corneo-scleral contact lens and a scleral ring has been developed that enhances/widens the palpebral fissure of a wearer's eye to enhance the cosmetic appearance of the wearer's eye (eyes) and can also be used to provide relief to patients suffering from drooping eyelids and/or ptosis. By enhancing the appearance of the wearer's eye it is meant that it makes the eye look more open and/or larger, and/or more alert. The novel prosthesis enhances the cosmetic appearance of the wearer by way of pushing up (elevating) the upper eyelid and/or also pushing down (depressing) the lower eyelid thus enlarging the wearer's palpebral fissure or aperture. The prosthesis has been shown to open the aperture of a wearer's eye by up to an additional 50% from its normal/natural eye aperture vertical dimension. Given that the average aperture of an individual's eye under the age of 40 would have a natural aperture having a vertical dimension (between the upper lid margin and the lower lid margin) of approximately 10.5 mm and that after the age of 40 the average dimension from the same points is approximately 9 mm, or approximately a 15% reduction in aperture size it can be seen that the prosthesis described herein can restore the youthful look the of wearer's eyes.The prosthesis comprises one or more, by way of example of: an augmentation in edge thickness, an internal incremental thickness zone, a regressive thickness zone, or an increased surface friction zone (either one) located at or external to the limbus, thus also external to the pupillary or optic zone which takes the form on the convex surface, by way of example only, a ring, (rings) band, (bands), partial rings (ringlets), dome (domes), island (islands), segmented region (regions), convex surface roughness/friction near or around the periphery of the lens and/or within or covering the aperture widening zone, truncation (truncations), overall thickening of the contact lens, larger diameter, and steeper base curve. The effect is to open up the palpebral fissure of the eye of the wearer and thus minimize the impact of blepharoptosis on visual performance and/or enhance the cosmetic appearance of the patient/wearer. The prosthesis when in the form of a corneo-scleral contact lens can be that of a soft contact lens or hybrid contact lens. When the prosthesis is in the form of a scleral ring as opposed to a contact lens the scleral ring comprises a central open aperture without optical power. The scleral ring can be made of a material found in one of a: hard contact lens, gas perm contact lens, hybrid contact lens. The incremental thickness region (zone, area) or a regressive thickness region (zone, area), or increased surface friction region (zone, area) for the prosthesis (being a contact lens or a scleral ring) can be one of: rotationally symmetric, rotationally asymmetric, elliptical arch like feature, and isolated islands. The elliptical arch (arches) like feature (features) can resembl
